\VILLIAM WV. MINER, OF NEWV HAVEN, CONNECTICUT, ASSIGNOR OF ONE- IIALF TO CHARLES S. MERSICK, OF SAME PLACE.

HORSESHOE-NAIL.

SPECIFICATION forming part of Letters Patent No. 41 7,066, dated December 10, 1889.

Application filed February 18, 1389. Serial No. 300,273. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM WV. MINER, of New I-Iaven,in the county of New Haven and State of Connecticut, have invented a new Improvement in I-Iorsesl1oe-Nails; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view of the blank from which the nail is made; Fig. 2, a flat side View of the nail; Fig. 3, an edge side view of the nail; Fig. 4:, a perspective view showing the nail as having an angular-shaped head.

This invention relates to an improvement in the manufacture of horseshoe-nails, the object being the construction of a nail which may be readily produced by machinery much simpler than that usually employed in the manufacture of horseshoe-nails and the nail itself be a better nail than that produced by such complicated machinery; and the invention consists in a nail having a head, a neck below the head round in transverse section, the body of the nail below the neck flat, the flat portion running into the round neck, and the round of the neck dying out in the head, as more fully hereinafter described.

In the production of the nail I take a nailrod square or other suitable shape in transverse section and of a size corresponding to the size required for the head. Then roll the blank or rod transversely to bring it into a round shape in transverse section, and in this rolling it is gradually reduced from the head a to the neck I), the neck Z) being of cylindrical shape, and from below the neck bsay as from the line cl downward-the body is rolled of 'a diameter so much less than the diameter of the neck, as seen in Fig. 1, as is required to produce the flat body of a width equal to the diameter of the neck. The body of this blank is then flattened from the junction of the neck and the body to the point, as seen in Figs. 2 and 3, bringing the'body e to a width substantially equal to the width of the neck, as seen in Fig. 2, and the requisite thickness, as seen in Fig. 3. The blank terminates in a conical-shaped point, which when flattened produces the required point, as repsented in Figs. 3 and 4E. The bevel and curve are also produced in the same operation of flattening the body.

The rolling operation, combined with .the flattening, thoroughly consolidates the metal and produces a nail solid and of suitable and uniform temper, ready for use. The head of the nail may be left of angular shape, as seen in Fig. 4, the nail being gradually drawn into cylindrical shape at the neck I? and the body the same as in the first illustration. In either case the nail has the same round neck and flat body, which produces a nail of desirable shape, the neck being much stronger and less liable to break than the usual construction of nails having flat necks. I prefer the round or cylindrical-shaped head, but do not wish to be understood as limiting the invention to the particular shape of the head, the rolled cylindrical neck and body, the body flattened to bring it to a width corresponding to the diameter of the neck, the flat dying out on the neck and the neck gradually running into the head constituting the essential features of my invention.

The nail is producedby automatic machinery, which will constitute the subject of an other application, not necessary to be described herein.

I claim 1. The herein-described horseshoe-nail, having a round or cylindrical neck gradually eX- pandin g into the head and a flat body in width corresponding substantially to the diameter of the neck, and the flat sides running into the round of the neck, substantially as described.

2. The herein-described horseshoe-nail, having a head of cylindrical shape,a neck of cylindrical shape of smaller diameter than the head, but graduallyexpanding onto the head, and a flat body in width corresponding substantially to the diameter of the neck, the flat sides of the body running into the round of the neck, substantially as described.

WILLIAM W. MINER.
